ROWE, OF STONINGTON, CONNECTICUT, ASSIGNOR TO THE ATWOOD MA- CHINE COMPANY, 01 STONINGTON, CONNECTICUT, A CORPORATION OF NEW JERSEY SPINNING AND TWISTING MACHINE Application filed October 4, 1930. Serial No. 486,889. I

This invention relates to improvements in spinning and twisting machines and has for its object to provide a novel mechanism for driving a plurality of spindles disposed in rows on opposite sides of the machine, together with means for automaticall keeping a predetermined tension on the driving belt without affecting the position of the belt with respect to the spindles actuated thereby.

Another object is to provide a driving and tension mechanism WhlCh is a complete and effective unit for a deck of spindles, so that several decksof spindles may be superposed in a frame, thereby minimizing the floor space occupied by the machine, increasin the utility and output of the machine, an facilitating ease and rapidity of removing andd replacing the driving belt, when desire Another object is to provide a driving and tension mechanism adapted to be mounted in an auxiliary frame ad acent one end frame of the machine, thereby obviating the use of take-up idlers for the belt and affording a greater number of spindles to be banked together in a deck between the end frames of the machine. 7

Another object is to provide certain improvements in the form, construction and arrangement of the several parts, whereby the above named and other ObJQCtS may effectively be attained.

A practical embodiment of my invention is represented in the accompanying drawings, in which ig. 1 represents a detail side elevation, partly in section, of one end of a spinning and twisting machine, having two decks of spindles superposed in a frame and my im-- proved driving and tension mechanism applied to each deck;

Fig. 2 represents a horizontal section taken in the plane of the line IIII of Fig. 1, looking in the direction of the arrows and Fig. 3 represents a detail vertical section taken in the plane of the line III-III of Fig. 1, looking in the direction of the arrows- In the drawings, I have illustrated the invention as applied to a spinning and twistbearings 16,

-The lower flanges respectively, which ing machine having two decks of spindles superposed in a frame, each deck being provided with a separate driving and tension mechanism, forming a complete unit and, as each unit is similar, I deem it only necessary to describe the mechanism included in a single unit.

The end frame of the machine is denoted by 1, and the. upper and lower pairs of rods or pipes denoted by 2, 3, which are secured to the end frames at 4, 5 respectively. The pairs of rods 2, 3 are disposed on opposite sides of the frame and extend throughout the length'of the machine. It is to be understood that a similar end frame serves to sup- .port the opposite end of the several rods, etc.

An upright 6 is spaced from the end frame 1 and connected thereto by horizontally disposed rails 7, 8, 9, 10, of which one end of each rail is fixed to the upri' ht 6, while the other end is secured to the en frame 1. The rails are disposed horizontall 'in upper and lower pairs, of which the rai s 7, 8 are substantially in alinement with the upper pairs of rods or pipes 2, 3 and the rails 9, 1O arranged to aline with the lower pairs of rods or pipes2, 3. Y

- A carrier is disposed between each pair of rails and arranged to slide lengthwise toward and away from the upright 6 and end frame 1. This carrier comprises a plate 11 havi a shaft 12 journaled in bearings 13, 14 at one end of the plate and a shaft 15 mounted in 17 at the other end of the plate. The shaft 12 is provided on its outer ends with anti-friction rollers 18, 19, while the shaft 15 carries pinions 20, 21.

Each pair of rails is formed with oppositely disposed upper flanges 22, 23 and oppositely arranged lower flanges 24, 25, between which upper and lower flanges the rollers 18, 19 and pinions 20,21 of the carrier move. are provided with racks with the pinions 20, 21,

racks terminate in flat portions 28, 29 for the rollers 18, 19, respectively, to travel on.

A motor 30 is suspended from the plate 11, by means of bolts -1 and its driving pulley 32 disposed above the plate 11 in position to 1 26, 27 which coact receivea driving belt 33. This belt 33 is 8.1-

7 while the other end has a loo-p 43 arranged to receive a weight 44 which depends therefrom. It will be understood that the shaft ranged .to ass through the end frame 1, around gui e ulleys 34, carried by suitable brackets xed to the rods or pipes 2, 3, respectively, and then lengthwise through the machine inposition to frlctionally engage the spindles 36, each of which is mounted in a bearing 37 carried by supports 38 secured to the rods or pipes 2, 3 by bolts 39.

i In order to maintain the driving belt at aconstant tension, the shaft 15 is extended out wardly so as to project through an elongated 1 slot 40 in the rails 7, 9 in position to receivega' counterbalance, in the present instance, in the form of a pulley 41 provided with a strap 42, one end of which is fixed to the pulley 4'1,

15 may also be extended throughelongated slots 45 in the rails 8, 10 and a similar pulley strap and counter-balance applied thereto so as to increase the tension on the belt if so desired.

From the foregoing it will be seen that a constant tension will be applied to the belt 33 through the weight 44tending to exert its pressure on the pulley 41 through the strap 42 apd hence to the shaft 15 which, in turn,

parting from the spirit and scope of my invention; and hence, I do not intend to be limited to the details herein shown and described, except as they may be included in the claims What I claim is 1.
